More significantly, it's explicitly a bash script (#! /bin/bash), whereas 
make-syscalls.sh uses #! /bin/sh and is run with $(SHELL).  Use of 
bash-specific syntax is only a bug when used in an sh script (#! /bin/sh, 
run with $(SHELL)).  Although since we don't document bash as a build 
requirement in install.texi, if any bash scripts are required for the 
build there's at least a documentation bug.
